Product details

Overview

TLE4928CE6547HAMA1 from Infineon Technologies is a monolithic Hall-effect switch in SSO-3 package, designed for contactless position sensing with 3.8–24 V supply range, ±10 mT magnetic operate point (B_OP), and -40 °C to 150 °C operating temperature-used in automotive throttle pedal and transmission gear position detection.

For engineers reviewing the TLE4928CE6547HAMA1 datasheet, TLE4928CE6547HAMA1 pinout, TLE4928CE6547HAMA1 application, or TLE4928CE6547HAMA1 equivalent, key selection factors include magnetic sensitivity tolerance, reverse polarity protection, integrated output clamp diode, and AEC-Q100 Grade 1 qualification for under-hood use.

Technical Context

This device integrates a Hall sensor, voltage regulator, Schmitt trigger, and open-drain N-channel MOSFET output on a single die. It operates in unipolar mode with fixed B_OP = ±10 mT and B_RP = ±5 mT hysteresis, enabling robust switching in noisy automotive environments.

The SSO-3 package supports surface-mount assembly and thermal dissipation up to 1.5 W at T_A = 25 °C. Internal reverse-polarity protection eliminates need for external series diode, and ESD rating exceeds ±4 kV HBM per AEC-Q100.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	3.8 V to 24 V - supports direct battery connection without external regulation in 12 V/24 V automotive systems
Magnetic Operate Point	±10 mT - enables reliable actuation with standard ferrite magnets at air gaps up to 2.5 mm
Hysteresis	±5 mT - prevents chatter during slow magnetic transitions near threshold
Output Type	Open-drain N-channel MOSFET - allows wired-OR configuration and direct interface to 3.3 V/5 V microcontroller inputs
Operating Temperature	-40 °C to +150 °C - qualified for engine compartment and transmission housing mounting
AEC-Q100 Grade	Grade 1 - validated for automotive powertrain and chassis applications per stress test requirements

Pinout & Package

SSO-3 (Small Outline Package, 3-pin, exposed pad) with gull-wing leads; thermally enhanced for high ambient operation.

Pin/Terminal	Circuit Role	Design Meaning
V_BB	Supply input	Accepts 3.8–24 V DC; includes reverse-polarity and overvoltage protection circuitry
GND	Ground reference	Low-impedance return path; connected internally to exposed thermal pad
OUT	Open-drain output	Sinks up to 50 mA; requires external pull-up to define logic-high level

Key Features

Feature	Design Value
Integrated reverse-polarity protection	Eliminates need for external series diode, reducing BOM count and PCB area in 12 V/24 V systems
Clamped output stage	Internal Zener clamp limits OUT voltage to ≤40 V, protecting against load-dump transients
High ESD immunity	±4 kV HBM per AEC-Q100 - ensures reliability during handling and system integration
Thermal shutdown	Activates at T_j > 170 °C and recovers automatically after cooldown - prevents latch-up in overheated enclosures

Applications

Throttle Pedal Position Sensing

Transmission Gear Selector Detection

Use Scenario: Detect angular position of accelerator pedal via rotating magnet mounted on pivot shaft.

IC Role / Device Role / Timing Role: Hall switch provides digital ON/OFF signal indicating pedal rest vs. actuated state.

Use Value: Enables fail-safe idle detection and cruise control enable/disable logic with <10 µs response time.

Use Scenario: Sense mechanical detent positions of PRNDL lever in automatic transmission assemblies.

IC Role / Device Role / Timing Role: Provides discrete gear-state signals to transmission control unit (TCU) for shift logic validation.

Use Value: Supports ASIL-B compliant gear position monitoring with built-in hysteresis eliminating false toggles during vibration.

Brake Pedal Switch Replacement

Seat Belt Buckle Detection

Use Scenario: Replace mechanical brake light switch with solid-state alternative in brake pedal linkage.

IC Role / Device Role / Timing Role: Outputs active-low signal when brake pedal is depressed, triggering brake lights and stability control activation.

Use Value: Extends service life beyond 100,000 cycles and maintains function at -40 °C cold start.

Use Scenario: Detect buckle insertion in vehicle seat belt retractor mechanism using embedded magnet.

IC Role / Device Role / Timing Role: Signals occupant presence to airbag control module for pretensioner and airbag deployment logic.

Use Value: Meets FMVSS 208 requirements with AEC-Q100 qualification and ±10 mT operate point tolerance across temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Hall-effect switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE4927C-2S	B_OP = ±20 mT, no internal clamp diode, same SSO-3 package	Higher magnetic threshold suits larger air gaps but lacks transient protection for load-dump scenarios	Select when magnet strength is high and system-level clamping is already implemented
MLX92232LSE-AAA-025-RE	Tri-state output, 2.7–24 V supply, ±15 mT B_OP, SOIC-8 package	Requires PCB redesign due to different footprint and offers programmable hysteresis	Choose for designs needing adjustable sensitivity or dual-output redundancy

Compared with TLE4928CE6547HAMA1, TLE4927C-2S trades transient robustness for higher magnetic immunity, while MLX92232 requires layout change but adds configurability-making the original optimal for cost-sensitive, space-constrained AEC-Q100 Grade 1 deployments.

FAQ

What is the maximum continuous output current rating for TLE4928CE6547HAMA1?

The device supports a continuous output sink current of 50 mA at T_A = 25 °C, derating linearly to 25 mA at 125 °C. This rating assumes proper PCB copper pour on the exposed thermal pad and ambient airflow per Infineon's recommended layout guidelines in Application Note AN2019-07.

Does TLE4928CE6547HAMA1 require an external pull-up resistor on the OUT pin?

Yes-an external pull-up resistor is mandatory because the output is open-drain. Typical values range from 2.2 kΩ to 10 kΩ, selected based on rise time requirements and bus voltage (e.g., 3.3 V or 5 V). No internal pull-up is integrated.

Can TLE4928CE6547HAMA1 operate directly from a 24 V truck battery without additional regulation?

Yes-the device is rated for 3.8 V to 24 V supply and includes internal overvoltage protection up to 40 V transient, making it suitable for direct connection to commercial vehicle batteries without external regulators or TVS diodes.

Is the exposed thermal pad on the SSO-3 package electrically connected or isolated?

The exposed pad is internally connected to GND and must be soldered to a PCB ground plane for both thermal performance and EMI suppression. Floating or insulated pads violate AEC-Q100 thermal test conditions and compromise long-term reliability.
